PLEASE NOTE

  • Some packages outside the L4T BSP can only be downloaded with an NVIDIA Developer Network login - in particular, the CUDA host-side tools.

    To use any packages that require a Devnet login, you must create a Devnet account and download the JetPack packages you need for your builds using NVIDIA SDK Manager.

    You must then set the variable NVIDIA_DEVNET_MIRROR to "file://path/to/the/downloads" in your build configuration (e.g., local.conf) to make them available to your bitbake builds. This can be the NVIDIA SDK Manager downloads directory, /home/$USER/Downloads/nvidia/sdkm_downloads

  • The SDK Manager downloads a different package of CUDA host-side tools depending on whether you are running Ubuntu 16.04 or 18.04. If you downloaded the Ubuntu 16.04 package, you should add

    CUDA_BINARIES = "cuda-binaries-ubuntu1604"

    to your build configuration so the CUDA recipes can find them. Otherwise, the recipes will default to looking for the Ubuntu 18.04 package.

  • CUDA 10.2 supports up through gcc 8 only. Pre-built binaries in the BSP appear to be compatible with gcc 7 and 8 only. So use only gcc 7 or gcc 8 if you intend to use CUDA. Recipes for gcc 8 have been imported from the OE-Core warrior branch (the last version of OE-Core to supply gcc 8) to make it easier to use this older toolchain.

    See this wiki page for information on adding the meta-tegra/contrib layer to your builds and configuring them for GCC 8.
